In this example:
The GridView.OptionsView.ShowButtonMode property speifies when the View displays editor buttons. Available modes include:
- Display editor buttons for all data cells.
- Display editor buttons for the focused cell.
- Display editor buttons for data cells within the focused row.
- Display editor buttons for the active cell editor.
This example handles the CustomDrawCell event to display editor buttons when hovering over a grid cell:
int rowHandle = -1;
private void gridView1_MouseMove(object sender, MouseEventArgs e) {
GridView view = sender as GridView;
GridHitInfo hi = view.CalcHitInfo(e.Location);
if(hi.InRowCell && hi.Column.FieldName == "Text")
rowHandle = hi.RowHandle;
else
rowHandle = -1;
view.Invalidate();
}
private void gridView1_CustomDrawCell(object sender, DevExpress.XtraGrid.Views.Base.RowCellCustomDrawEventArgs e) {
if(e.Column.FieldName == "Text" && e.RowHandle == rowHandle) {
GridCellInfo cellInfo = e.Cell as GridCellInfo;
ButtonEditViewInfo info = cellInfo.ViewInfo as ButtonEditViewInfo;
Rectangle textRect = info.MaskBoxRect;
textRect.Offset(e.Bounds.X, e.Bounds.Y);
EditorButtonObjectInfoArgs args = new EditorButtonObjectInfoArgs(e.Cache, info.Item.Buttons[0], e.Appearance);
Rectangle minBounds = info.EditorButtonPainter.CalcObjectMinBounds(args);
args.Bounds = new Rectangle(e.Bounds.Right - minBounds.Width, e.Bounds.Y + (e.Bounds.Height - minBounds.Height) / 2, minBounds.Width, minBounds.Height);
info.EditorButtonPainter.DrawObject(args);
e.Cache.DrawString(e.DisplayText, e.Appearance.Font, e.Appearance.GetForeBrush(e.Cache), textRect, e.Appearance.GetStringFormat());
e.Handled = true;
}
}
